Wow this and the diagram match up pretty well, and both look good!The solar panel breakers are right there in that same compartment so I can completely isolate the inverter from power if I need to work on it. Maybe I installed it when I was having issues with my SOK BMSs going into protect all the time. That issue has been solved with the BattleBorn current limiter so I don't think I need that inverter disconnect switch anymore. Just trying to simplify things.
I also don't need the multi control panel so might just remove that, too.

The positive wires are the same exact size. The negative cables are within 3/4". Not gonna do any weird stacking to get it "exact".You should adjust your battery wiring as well. If you're running cables to them both then they should be the same exact size. This way one battery isn't closer than the other. Typically with 2 batteries you just run the positive from one and the negative from the other then wire both batteries together. With yours you'd need to stack the lugs on the battery terminals (bigger batteries usually have 2 terminals for each).
I'm digging those colored wires BTW
Mmm... Red Green Blue - looks like they should be connected to a giant video displayI'm digging those colored wires BTW
The red and blue ones on the far left are the low point drains for the freshwater system.Mmm... Red Green Blue - looks like they should be connected to a giant video display
Gotcha. They look a lot different in the pic. The criss cross makes more sense because regardless you're still limited to 4/0 wire amps as they combine at the fuse. But I don't think it really matters. I'd rather the whole system be equal and risk voltage drop (that's recorded on the shunt) over batteries not being perfect and having different cycle counts months/years laters.The positive wires are the same exact size. The negative cables are within 3/4". Not gonna do any weird stacking to get it "exact".

I had them criss cross applesauce and folks here convinced me that was the wrong way.

I do this via breakers, let's me protect the wire from battery -> inverter as well.I guess to let you work on the inverter without turning off the solar?
Have these breakers as well, but it's nice to have specific inverter breakers to avoid loosing PV -> battery charging while working on the inverterBut you can just turn off the mppts remotely.
You really shouldnt need to be working on the inverter or anything once setup though. And if you're having issues I'd rather have everything off completely to troubleshoot.I do this via breakers, let's me protect the wire from battery -> inverter as well.

If only it were so.... I have a pair of heavy (175lb) inverters and after 5 years one of them failed - had to go thru hoops to replace / repair - and was nice to have breakers to shut off the battery while working on things.You really shouldnt need to be working on the inverter or anything once setup though.
Yeah a battery disconnect is needed but we're talking about vehicle systems here and a battery disconnect plus an inverter disconnect is just redundant.If only it were so....

Agree that space can be tight - for example, I also have a trailer ->camper w/inverter and breakers (battery -> inverter, and other) which were helpful in recent work adding a 2nd battery.Yeah a battery disconnect is needed but we're talking about vehicle systems here and a battery disconnect plus an inverter disconnect is just redundant.
Also in a vehicle inches matter and we don't have walls with tons of space. OPs photos are pretty typical of a bay.
